Spectrum

This widget presents multiple spectra on the same graph. Each of the spectra may have been taken on different machines, points, acquisition modes or machine captures, and therefore allows multiple data sources to be used. For each of them the Widget can display in real time the spectra captured by the data acquisition hardware, as well as the last "n" spectra stored in the database.

Funcionality

Widget components and operation are described below.

Icon	Name	Description
	Play/Pause	Play button allows to put the widget in online mode, automatically updating the last measurements taken by the acquisition hardware. Pause button stops the online mode, so the Widget will stop updating the values taken by the hardware.
	Previous	Displays the measurement previous the widget visualization of those stored in the database.
	Next	Displays the measurement after the widget visualization of those stored in the database.
	Timeline	It displays the acquisition history timeline, which provides quick and easy access to the measurements recorded on a given date.
	Information	Displays or hides the spectrum information window. This window displays point, machine and spectrum information. Machine: name, status and alarm condition during capture, and its rotational speed. Point: name, DC value provided by the sensor (bias). Spectrum: overall value, acquisition mode, minimum and maximum frequency, number of lines and date and time of measurement.
	Cursors	Allows you to add up to 10 different cursors in the spectrum. Each cursor will be assigned a different color by default.
	Single Cursor	Selects the single cursor type (single frequency).
	Harmonics	Selects the harmonics cursor type, which allows you to mark the harmonics of a frequency in the spectrum.
	Lateral bands	Selects the sideband cursor type, which allows to display the equidistant frequencies on both sides of a reference and their harmonics.
	Cursors information	Displays or hides the cursor information window, which shows the data of the displayed cursors in the spectrum (amplitude, frequency, units). For sideband cursors it also shows the amplitude and frequency of the reference and the distance to the main cursor.
	Clear all	Removes cursors and fault frequencies displayed on the spectrum.
	Failure frequencies	Select from a drop-down list the fault frequencies defined in the dynamic point to be displayed on the spectrum. The name of the fault frequency appears on the graph.
	Magnitude change	Select the magnitude to display the spectrum (acceleration, velocity, displacement), integrating or deriving the signal as required.
	Change in scale	Switches between linear or logarithmic scale.
	Waveform	Displays the waveform stored in the capture for the same point and spectrum acquisition mode.
	Parameter Matrix	Displays the parameter matrix of the machine capture on which the spectrum was measured, thus showing all the parameters of the dynamic points of the machine and the measurements of the static points.
	Reset zoom	Resets the graph zoom.

Configuration

The Widget, once created, must be configured to select the data source and display options. To do so, select the Configuration icon, located in the upper right corner.

The following window shows the configuration options:

The Widget allows multiple spectra to be displayed on the same graph, in which case several data sources must be configured. For this purpose, the configuration window has a bar on which several data sources can be added and the one to be configured can be selected by means of the corresponding tabs.

To create a new data source, click on the following button:

This will create a new tab, automatically assigning a color to it and displaying the particular configuration options for this measurement.

To access the options for the other data sources just click on the corresponding tab.

The following table shows the general widget configuration options as well as the particular ones for each data source or measurement that the graph will show.

Field	Description
Nombre (name)	Widget identifier. This text appears in the upper left part of the widget.
Máquina (machine)	Selects the machine of the measurement displayed in the widget.
Visible	Defines if the corresponding spectrum graph will be visible or hidden.
Color	Selects the color to be used in the spectrum graph.
Punto dinámico (Dynamic point)	Selects from a drop-down list the machine point and component to which the spectrum measurement to be displayed belongs.
Modo de adquisición (Acquisition mode)	Selects from a drop-down list the spectrum acquisition mode to be displayed by the widget.
Anteriores y posteriores (Previous and subsequent)	Selects desired spectrum date, as well as the previous and next number of spectra to be displayed.
Entre fechas (between dates)	Selects the date range for displaying the spectra, as well as the maximum number of spectra to be displayed.
Personalizado (Customized)	Saves the selected dates in the timeline, allowing to delete them all.
Eje Z (Z-axis)	Selects Z-axis sorting. It depends on three factors: sort field (time, velocity) type (ascending, descending) spacing between spectra (equidistant, proportional)
Vista (View)	Selects from a drop-down menu the default view type: multispectrum stack 3D
Unidad de medida (Unit of measurement)	Selects from a drop-down list the units of measurement in which the amplitude values of the spectrum will be represented.
Tipo de detección (Detection type)	Selects from a drop-down menu the detector associated to the amplitude (RMS, P-P, Peak) with which the amplitude values of the spectrum will be represented.
Órdenes (Orders)	Displays the X-axis in frequency or in orders.
Unidad de frecuencia (Frequency unit)	Selects from a drop-down list the unit in which the scale and frequency values will be displayed.
Número de armónicos por defecto (Default number of harmonics)	Defines the harmonic cursors number of the main cursor, as well as the sidebands number on both sides of the central cursor in the case of sideband type cursors.
Actualizar forma de onda en (Update waveform in)	Selects from a drop-down field the linked widget in which the waveform associated with the spectrum will be presented. The drop-down presents the list of waveform widgets on the desktop.
Actualizar matriz de parámetros en (Update parameter matrix in)	Selects from a drop-down field the linked widget in which the parameter matrix of the machine capture on which the spectrum was taken will be updated. The drop-down presents the list of parameter matrix widgets on the desktop.
Grid line	Displays a grid over the graph.
Mostrar toolbar (Show toolbar)	Displays the widget toolbar at all times. This toolbar is always displayed when maximized. When not maximized it will be displayed depending on what is selected in this option.
